osml-data-intake 1.1.2

Package to run the osml image intake component service.

OSML Data Intake

Overview

This application facilitates the processing, conversion, and management of satellite imagery metadata as part of the OversightML (OSML) framework and can be deployed as part of the OSML guidance package. It leverages the GDAL library and integrates with Amazon S3 for seamless storage and sharing to provide imagery metadata to other service components. Below is an overview of the main features:

Intake

The intake processes metadata from satellite imagery files, such as image dimensions and geographical coordinates. Uploads auxiliary files and metadata to Amazon S3 and serves converted meta-data into STAC items on an SNS topic.

Ingest

Ingests SpatioTemporal Asset Catalog (STAC) items placed on an SNS topic into via the STAC Fast API database logic.

STAC

The STAC component powers a Fast API front end that allows for interacting with the OpenSearch database that houses the processed geospatial assets.

Getting Started

Prerequisites

First, ensure you have installed the following tools locally

1. aws cli
2. docker
3. tox

Installation Guide

1. Clone osml-data-intake package into your desktop

git clone https://github.com/aws-solutions-library-samples/osml-data-intake.git

2. Run tox to create a virtual environment

cd osml-data-intake
tox

Documentation

You can find documentation for this library in the ./doc directory. Sphinx is used to construct a searchable HTML version of the API documents.

tox -e docs

Testing Locally

After setting up your environment, you can verify your setup by sending a test message to the SNS topic that will trigger your application workflow. This is useful for ensuring that your processing pipeline works correctly with a given image.

Prerequisites:

• Ensure that your AWS credentials are configured properly in the environment.
• Make sure that you have the AWS CLI installed and configured.
• Deploy the osml-data-intake infrastructure using the guidance package

Testing Data Intake

Run the Test Command:

1. Replace the following with your specific details:
   Topic ARN: Update the --topic-arn argument with the ARN of the SNS topic that triggers your application.
   S3 URL: Replace the S3 URL in the --message argument with the URL of the bucket or image file you want to test.

2. Execute the following command, substituting your actual values:

   python3 bin/stream/stream_cli.py --topic-arn <YOUR_TOPIC_ARN> --s3-uri <YOUR_S3_URI> --item-id <DESIRED_ITEM_ID>
   

3. Validate Expected Output:
   This will trigger the processing of the specified image file in your application. Verify that the auxiliary files are generated and uploaded to your configured S3 bucket, and ensure that the logs indicate a successful run.

Testing Data Catalog

1. To put a test item directly in your STAC catalog, update the following command and run it with your endpoint:

   curl -X "POST" "<<YOUR_API_URL>>/data-catalog/collections" \
        -H 'Content-Type: application/json; charset=utf-8' \
        -H "Authorization: Bearer $TOKEN" \
        -d $'{
     "type": "Feature",
     "stac_version": "1.0.0",
     "id": "example-item",
     "properties": {
       "datetime": "2024-06-01T00:00:00Z",
       "start_datetime": "2024-06-01T00:00:00Z",
       "end_datetime": "2024-06-01T01:00:00Z"
     },
     "geometry": {
       "type": "Polygon",
       "coordinates": [
         [
           [-104.99404, 39.75621],
           [-104.99404, 39.74575],
           [-104.97342, 39.74575],
           [-104.97342, 39.75621],
           [-104.99404, 39.75621]
         ]
       ]
     },
     "links": [
       {
         "rel": "self",
         "href": "http://example.com/catalog/example-item.json",
         "type": "application/json"
       },
       {
         "rel": "root",
         "href": "http://example.com/catalog/catalog.json",
         "type": "application/json"
       }
     ],
     "assets": {
       "thumbnail": {
         "href": "http://example.com/thumbs/example-item.jpg",
         "title": "Thumbnail",
         "type": "image/jpeg"
       },
       "data": {
         "href": "http://example.com/data/example-item.tif",
         "title": "Geospatial Data",
         "type": "image/tiff; application=geotiff"
       }
     },
     "collection": "example-collection-3"
   }'
   

2. To get your item run:

curl -X "GET" "<<YOUR_API_URL>>/data-catalog/collections"`

Submitting a Bulk Ingest Job

This workflow is tailored for efficiently processing large quantities of images stored in an S3 bucket and integrating them into a STAC catalog using AWS services. It is designed to streamline the ingestion process for thousands of images awaiting cataloging.

Prerequisites:

• Ensure AWS credentials are correctly configured.
• Install and configure the AWS CLI.
• Active STAC Catalog service.
• S3 Input and Output Buckets configured.

1. Build and push a Docker container to your ECR repository:

./scripts/build_upload_container.sh

2. Create an execution role using the following command:

aws iam create-role \
    --role-name BulkIngestSageMakerExecutionRole \
    --assume-role-policy-document '{
        "Version": "2012-10-17",
        "Statement": [
            {
                "Effect": "Allow",
                "Principal": {
                    "Service": ["sagemaker.amazonaws.com", "opensearchservice.amazonaws.com"]
                },
                "Action": "sts:AssumeRole"
            }
        ]
    }' \
    --description "Allows SageMaker to execute processing jobs and specific S3 actions." \
    && aws iam attach-role-policy \
        --role-name BulkIngestSageMakerExecutionRole \
        --policy-arn arn:aws:iam::aws:policy/AmazonS3FullAccess \
    && aws iam attach-role-policy \
        --role-name BulkIngestSageMakerExecutionRole \
        --policy-arn arn:aws:iam::aws:policy/AmazonSageMakerFullAccess

Retrieve the full ARN of the custom SageMaker role:

aws iam get-role --role-name BulkIngestSageMakerExecutionRole --query 'Role.Arn' --output text

3. Head over to Bulk Configuration README.md on configuring your bulk job

4. Execute the SageMaker Processing Job:

   python3 ./bin/bulk/bulk_cli.py \
       --s3-uri <S3 Input Bucket> \
       --region <AWS Region> \
       --output-bucket <S3 Output Bucket>
   

   Example command:

   python3 ./bin/bulk/bulk_cli.py \
       --s3-uri s3://test-images-bucket \
       --region us-west-2 \
       --output-bucket s3://<id>-output-bucket
   

5. To monitor the ProcessingJob status, there are two ways:

   • Navigate to the SageMaker Processing Console: AWS -> SageMaker -> Processing (Left Sidebar) -> Processing Job, and monitor it there.

   • Alternatively, monitor using the command:

   python3 bin/bulk/check_job.py --region us-west-2 [--job name]
   

   Note: Replace [--job name] with your specific job name if needed.

6. Cleanup when completed:

   • Delete Bulk Ingest Container

     aws ecr batch-delete-image --repository-name data-bulk-ingest-container --image-ids "$(aws ecr describe-images --repository-name data-bulk-ingest-container --query 'imageIds[*]' --output json)"
     
     aws ecr delete-repository --repository-name data-bulk-ingest-container --force
     

   • Delete Custom Execution Role ARN

     aws iam delete-role --role-name BulkIngestSageMakerExecutionRole
